Motor protection circuit breaker, size S00, 0.8 A, CLASS 10
The Siemens 3RV2011-0HA10-ZW96 is a SIRIUS motor protection circuit breaker in size S00, designed to protect a motor drawing up to 0.8 A full-load current. The adjustable overload release covers 0.55 to 0.8 A, and the instantaneous magnetic short-circuit trip responds at 10 A. CLASS 10 trip class means it will trip within 10 seconds at 7.2× the set current — fast enough to protect a standard induction motor during a locked-rotor event without nuisance tripping on normal start-up. Rated for system voltages from 20 to 690 V AC, this breaker delivers a 100 kA breaking capacity across the 240 V to 690 V range (-). That SCCR rating means it can safely interrupt a fault current up to 100,000 A without welding contacts or rupturing — critical for high-fault installations where upstream breakers are sized above 65 kA. The unit snaps onto a 35 mm DIN rail per DIN EN 60715, fitting standard panel layouts.
